What problem does it solve? When working with spec-driven development, it is easy for code to drift away from the tasks, requirements, and design decisions recorded in change artifacts. This Skill audits an implementation against its OpenSpec change artifacts so gaps are caught before the change is archived. ## Core Features & Use Cases - Three-Dimension Verification: Checks completeness (task checkboxes, spec coverage), correctness (requirement implementation, scenario coverage), and coherence (design adherence, code pattern consistency). - Structured Report: Produces a markdown verification report with a summary scorecard and issues grouped as CRITICAL, WARNING, or SUGGESTION, each with actionable recommendations and file references. - Graceful Degradation: Adapts checks based on which artifacts exist (tasks only, tasks plus specs, or full artifacts including design). - Use Case: Before archiving a spec-driven change, run the verification to confirm all tasks are checked off, every requirement has implementation evidence, and the code follows the recorded design decisions. ## Quick Start Verify that my current OpenSpec change implementation is complete and ready to archive.
